I had my uncle give me the bike I learned to ride on. It is a 92 tw200. I pulled the carburetor. When I tore it down to clean it the insides are gummed up so bad that nothing I have tried has removed it. Plus the throttle needle is stuck. I am wondering if anyone has a carburetor for sale or has any advice on what I need to do. Plus I also need a gas tank petcock valve.
